FLY-TRAP.

Specification of Letters Patent.

Application filed August 15, 1910. Serial No. 577,815.

Patented 'Apr. 18, 1911.

To all whom it may concern:

Be it known that we, JACOB G. Voo'r and JOHN A. JOHNSON, citizens of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Imiprovements in Fly-Traps, of which the specification.

This invention relates to fly traps; and

the object of the invention is to provide a device which is simple in construction, cheap to manufacture and one having the capacity gor catching and holding a large num er of res.

A further object of the invention is to provide a fly trap wherein as the files are lured under and away from the point of entrance they are enticed into the trap from which escape is impossible.

We accomplish the objects of. the mvention by means of the fly trap illustrated in the accompanying drawings, forming a part hereof, in wh1chj Figure 1 is a perspective View of our 1mproved fly trap. Fig. 2 is a fragmentary detail central vertica sectional view of the upper and lowerportions of the trap. Fig.

3 is a perspective view of the pyram dal y formed base of the trap, the upper or cage portion thereof being omitted.

The fly trap comprises a rectangular skeleton frame, consisting of the upper and lower rectangular sections 1 and 2, andthe u rights 3 which are usually placed at t e "corners and form the supports for the sections 1 and 2 and against which the wire netting is nailed. The sides, ends and top of this skeleton frame are inclosed by means llowlng is a ot-"suitable wire netting, th fi ame -so in 4o 'closed forming a recqstaclcwr cage for receiving the flies after being admitted through the base of the trap. The uprights 3 pro ect slightly below the lower member 2 of the skeleton frame so that the trap is slightly elevated above the floor line and provides the in ress or entrance to the trap from all sides t ereon. Inclosin the lower end of the cage is a pyramida ly formed base 7 which is provided with the centrally solocated opening or window 8 for admission of ii ht to the chamber below said base. The ase 7 is formed in the sha evof a.

pyramid to provide a chamber be ow and as composed of metal or wood so that the fldor surface beneath the marginal edge of I the ppening 8 and the outer marginal edge "from the cage to the base.

of the base casts a shaded belt around said opening. The floor around and partiall under the trap-between imaginary lines and B-is strewn with suita bait to attract the flies. As the bait extends along t e floor but a short distance beyond the on marginal edge of the base 7 the fl-ies in vourmg the bait, will belured under the base, after which the general direction of movement will be toward the bright spot on the floor beneath the window or opening 8. After reaching the central and lig ted portion of the floor the flies willnot attempt to recross the shaded portion of the floor between the ed e of the opening 8. and the outer edge of't e base to the point of entranee, but the general movement will instmctively .be-tow'ard the point of greatest illumination which point lathe openi 8. 76 When the flies reach the opning 8 furt er pro ess is impeded by means of the wire netting 10 which is -gp1aced over the opemng 8. As a1 argeopen1ng, such as 8, must be provided to permit sufiicient illumination 80 of the chamber below the base to induce the flies to enter said chamber, such 0 ening, without such overlaid netting W0 (1 also permit the flies'to pass uninterru tedly back 0 provide means, however, for enabling the flies to work their way from in under the wire netting 10 into the cage above, which is accomplished by exten in the wire netting 10 edges of the opening 8 from which pain a short distance beyon one or more of tlli%e 9,0/' netting is bent doygy n zwydandse uied to thesurface of the-ba This arrangement in bendingfthe netting 10 provides the transversely extending run or passagewa s 12 between said wire netting 10 and t e outer surface of the base 7 The flies are admitted to the pas'sa eways 12 by means of a. plurality of note cs 14 arranged in the ad'acent marginal edges of the opening 8, an as they walk along the underneath surface of the netting 10 they will ultimately t1pass outthrough the notches 14 and into elrrun or passageways 12. After enteringthepassageways they move alon until they 'reachthe ends thereof at whic points ey are free to fly upward within the cage portion of the trap. As the upper portion of the cage is well i hted there is no disposition on the part 0 the flies to seek their way out along the circuitous route and through the shaded chamber below the base 7, as it is natural for the flies to remain near the top of the cage.

It will be noted that after the fly trap is set the operation ofcatching flies is carried on uhinterruptedly, and the more flies that are within the cage the greater becomes the attraction as the flies within act as a decoy for those Wl'tlIOHiJ, As the operation of catching flies continues the process of flies dying is a natural consequence during the same period of time. When the flies die they drop to the bottom of the cage where they'are caught between the slanting sides of the base 7 and the wire netting forming the sides of the cage. When a quantity of dead flies have accumulated in the bottom of the cage the trap is shaken or agitated which causes the flies to settle at the top of the cage, at which time the base 7 may be detached from the cage, by loosening the hooks 16, allowing the dead flies to roll out Without liberating any of the live ones,

4 Havin thus fully described our said inl. Afly trap comprisin ention, what we desire to secure-by Letters 25 a Patent, EE;- 7 J an open bottom cage having its sides an top closed with rfoiated material, a base for said cage an inwardly and upwardly extending wall and, provided with a light opening in itstop, and notches along opposite edges of said opening, perforated material overa V overlying both theopening and'notches, pas
